grailbio / grit Goto Github PK

This looks like to be exactly the type of tool I need, however, I'm getting some errors using it.

The monorepo has many projects, and has been developed since 2017.

I want to move each of those projects into separate repos, while still maintaining the monorepo for legacy CI purposes.

We will call the monorepo, repoA

I tried creating a new repo for just one of the projects to start with:

First I tried splitting it out initially using:

git filter-branch --prune-empty --subdirectory-filter project/app  master

into a new repo, repoB

https://help.github.com/en/articles/splitting-a-subfolder-out-into-a-new-repository

But when I try to sync with grit from A to B, I get errors that the files already exist.

error: .editorconfig: already exists in index

etc.

So I tried an empty repo - error: master branch not found.

So I added a file that didn't exist to it, and then tried syncing from A to B, this time got a different error - it copied commits from 2017 through July 2018, and then fails at one of them.

Any suggestions on best practices for getting initial sync going?
